The VISTAKON Contact Lens Visibility Tint with UV Blocker is tinted blue using Reactive Blue Dye #4 to make the lens more visible for handling. A benzotriazole UV-absorbing monomer is used to block UV radiation. The transmittance characteristics are less than 1% in the UVB range of 280nm to 315nm and less than 10% in the UVA range of 316nm to 380nm. The VISTAKON Contact Lens is a hemispherical or hemitoric shell. | | |-----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Intended Use | Spherical lens | The VISTAKON Contact Lens is indicated for daily wear for the correction of refractive ametropia (myopia and hyperopia) in aphakic or non-aphakic persons with non-diseased eyes who may have 1.00 D of astigmatism or less. | | | Multifocal lens | The VISTAKON MULTIFOCAL Contact Lens is indicated for daily wear for the correction of distance and near vision in presbyopic aphakic or non-aphakic persons with non-diseased eyes who may have 0.75 D of astigmatism or less. | | | Toric lens | The VISTAKON TORIC Contact Lens is indicated for daily wear for the correction of visual acuity in aphakic or non-aphakic persons with non-diseased eyes that are hyperopic or myopic and may have 10.00 D of astigmatism or less. | | | Toric Multifocal lens | The VISTAKON TORIC MULTIFOCAL Contact Lens is indicated for daily wear for the correction of distance and near vision in presbyopic aphakic or non-aphakic persons with non-diseased eyes who may have 10.00D of astigmatism or less. | | | Eye care practitioners may prescribe the lens for single-use disposable wear or for frequent/planned replacement wear, with cleaning, disinfection and scheduled replacement (see "WEARING SCHEDULE"). When prescribed for frequent/planned replacement, the lens may be disinfected using a chemical disinfection system only. | | Continued on next page {2}------------------------------------------------ The VISTAKON (lenefilcon A) Contact Lens is classified into FDA Group II Characteristics for contact lens materials. The predicate device is classified into FDA Group IV. The predicate device was chosen because the water content and Dk value are the same as the subject device, the predicate device is available in similar base curve and diameter configurations and both subject and predicate devices are visibility tinted. The characteristics of the VISTAKON (lenefilcon A) Contact Lens are compared to the characteristics of the predicate device in the following table. | | VISTAKON (lenefilcon A)<br>Contact Lens Visibility Tint<br>with UV Blocker | | NewVues® (vifilcon A) Soft<br>Contact Lens | | |-------------------------|----------------------------------------------------------------------------|-------|--------------------------------------------|-------| | | Measured | Label | Measured | Label | | Water Content, % | 55 | 55 | 56 | 55 | | Refractive Index @ 20°C | 1.41 | 1.41 | #1.41 | 1.415 | | Dk, edge corrected | 17 | 16 | 18 | 16 | | Dk, non-edge corrected | 22 | 21 | 22 | 16 | | Color (if tinted) | Blue | Blue | Blue | Blue | | Base Curve, mm | 8.86 | 8.84 | 8.5 | 8.5 | | Diameter, mm | 14.10 | 14.05 | 14.3 | 14.0 | | Power, D | -0.79 | -0.74 | -1.02 | -1.00 | Dk units = x 10-11 (cm²/sec) (ml O2/ml x mm Hg) * edge correction method not identified in CIBA Vision® labeling # calculated from water content | Non clinical<br>Studies | Included as non clinical studies are<br>• chemistry,<br>• toxicology, lenses and package,<br>• microbiology | | |----------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Chemistry | Material property data were generated on the subject device and the predicate<br>device. The data for both devices reflect properties of Group II and Group IV<br>lenses, respectively. The lens care product manufacturers have previously<br>shown compatibility of Group II and Group IV lenses with their products.<br><br>The shelf-life stability for VISTAKON (lenefilcon A) Contact Lenses is<br>based upon stability protocols included with this notification or referenced.<br>Studies were conducted to determine the leachable monomers from the<br>subject device. | | | Toxicology,<br>lenefilcon A<br>lens material | In accordance with the May 1994 Guidance Document for Daily Wear contact<br>lenses, toxicology studies have been conducted on the VISTAKON<br>(lenefilcon A) soft (hydrophilic) Contact Lenses Clear and Visibility Tint<br>with UV blocker. The results are summarized below: | | | | Cytotoxicity<br>Test | The negative controls and the positive controls performed as<br>anticipated. Under the conditions of this study, the test article<br>showed no evidence of causing cell lysis or toxicity. The test<br>article was not cytotoxic and passed this ISO study. | | | Ocular<br>Irritation<br>Study in the<br>Rabbit | Under the conditions of this study, there was no evidence of<br>significant irritation in the test eye or control eye of any<br>rabbit. The SC and CSO test article extracts would not be<br>considered irritants to the ocular tissue of the rabbit. | | | Acute<br>Systemic<br>Toxicity in<br>the Mouse | Under the conditions of this study, there was no mortality or<br>evidence of significant systemic toxicity from the extracts.<br>Each test article extract met the ISO requirements. | | Toxicology,<br>package<br>materials | No additional toxicology studies have been conducted on the plastic primary<br>packaging materials, as the materials are the same as those previously tested<br>and reported under N18-033. | | | Microbiology | The lens sterilization process, moist heat sterilization, has been validated to<br>deliver a minimum SAL of 10-6. The lens care product manufacturers have<br>established a reasonable assurance of disinfection efficacy of their care<br>products with the lens groups for which they are approved. There are shelf-<br>life stability data that support lens sterility throughout the shelf-life claimed<br>for the product. | | | Clinical studies | The safety of the lens material in the spherical design has been confirmed<br>through a clinical trial for daily wear contact lens materials with a new USAN<br>name according to the Premarket Notification (510(k)) Guidance Document<br>for Daily Wear Contact Lenses (May 1994). The study evaluated at least 50<br>patients with a 2:1 ratio of subject device to predicate device for three (3)<br>months. Parameters measured included adverse reactions, symptoms, | | | Clinical studies | problems and complaints, slit lamp evaluations, visual acuity, lens wear time,<br>fit assessment and discontinuations. The VISTAKON (lenefilcon A) trial<br>contact lens was found to be at least substantially clinically equivalent to the<br>predicate device. | | | Conclusions<br>drawn from<br>studies | Validity of<br>Scientific Data | Toxicology studies were conducted by a contract<br>laboratory under Good Laboratory Practice Regulations.<br>Microbiology, chemistry, shelf-life stability, and<br>leachables studies were conducted by in-house laboratories<br>and followed scientific protocols. The data were<br>determined to be scientifically valid under 21 CFR 860.7. | | | Substantial<br>Equivalence | The data presented in this Premarket Notification support<br>the subject device is as safe, as effective and performs as<br>well as or better than the predicate device when used in<br>accordance with the labeled directions for use and for the<br>requested indication. | | | Risk and Benefits | The risks of the subject device are the same as those<br>normally attributed to the wearing of soft (hydrophilic)<br>contact lenses on a daily wear basis. The benefits to the<br>patient are the same as those for other soft (hydrophilic)<br>contact lenses. | Continued on next page {3}------------------------------------------------ Continued on next page . {4}------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ {5}------------------------------------------------ Image /page/5/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
